1 RMOD - Analyses and Languages Constructs for Object-Oriented Application Evolution

Even though blockchain is mostly popular for its cryptocurrency, smart contracts have become a very prominent blockchain application. Smart contracts are like classes that can be called by client applications outside the blockchain. Therefore it is possible to develop blockchain-oriented software (BOS) that implements part of the business logic in the blockchain by using smart contracts. Currently , there is no design standard to model BOS. Since modeling is an important part of designing a software, developers may struggle to plan their BOS. In this paper, we show three complementary modeling approaches based on well-known software engineering models and apply them to a BOS example. Our goal is to start the discussion on specialized blockchain modeling notations.
